SPECIFICATION forming part of Letters Patent No. 768,316, dated August23, 1904.

Application filed June 6, 1908. Serial No. 160,820. (No model.) i

,To all whom it may concern:

Be it known that we, HERBERT H. SMITH and FRANK B. DUNN, citizens oftheUnited States, and residents of Oonneaut, Ashtabula county, and State ofOhio, have invented a-new and useful Improvement in Brick FacingMachines, of which the following is a specification, the principle ofthe invention being here in explained and the best mode in which we havecontemplated applying that principle, so as to distinguish it from otherinventions.

Our invention relates to a device for facing one surface of a brick-thatis, removing a portion of one brick-surface in order to impart theretowhat is commonly known as a rock-face.

The object of the invention is to efliect such an operationautomatically by means of machinery and in an economical and efficientmanner.

Said invention consists of means hereinafter fully described, andparticularly set forth in the claims.

p The annexed drawings and the following description set forth in detailcertain means embodying the invention, thedisclosed means, however,constituting but one of various forms in which the principle of theinvention may be used.

In said annexed drawings, Figure I represents a plan' view of a deviceembodying our invention, a part of the base plate being broken away.Fig. II represents a vertical axial section of a portion of saidmachine, taken upon a plane indicated by line 2 2, Fig. I. Fig. IIIrepresentsavertical axial section of a portion of said machine, takenupon the'plane indicated by line 3 3, Fig. I.. Fig. IV represents thebottom plan view of the gear-ring forminga part of such machine. Figs.V, VI, VII, and VIII represent vertical sections taken upon the planesindicated by the lines 5 5, 6 6, 7 7 and 8 8, Fig. IV, respectively.Fig. IX represents in perspective a portion of said device with partsremoved, the base-plate being shown broken away.

Upon the base-plate A is formed, by means means of suitable.drivingpulleys.

hearing, which receives the lower end of a rotatable ring B, Fig. IX.This ring is formed upon its outer lateral surface with teeth 6, whichmesh with the worm O, secured upon the rotatable shaft 0, mounted insuitable bearings upon the base-plate A and rotatedNby ot It will beseen that the rotation of the shaft and worm will effect a rotation ofthe ring B.

Formed or secured upon the base-plate are a series of blocks (0 Fig. IX,provided with suitable grooves forming slideways for parts reciprocabletoward and from the center of the base-plate, aswill be furtherdescribed. Such center of the base-plate is formed with an opening a ofa rectangular cross-section, as

shown,-and of dimensions such as will permit a brick to fall or droptherethrough. In these slideways are located two clamping-blocks D,Figs- II and III, which are reciprocable toward and from the center ofthe base-plate.

"Upon the top of each such block and having a sliding bearing thereon isa knife E, which is secured to a reciprocable block E and adjustablerelatively thereto by means of set-screws and e, as shown in Figs. 'Iand II. These blocks E are held in position by means of gib-plates a asshown in Fig. I. It will be seen that the clamping-blocks and knives maybe'reciprocated toward and from the center independently of each other.Recipro'cable at right angles to the knives E are two knives E mountedin bearings formed in the blocks a and held down by means of thegib-plates a, Fig. I. These knives are secured to the space, four slidesF, Figs. -I, II, and IX, are

provided, which are also reciprocable toward and from the center of theplate. These slides may be caused to project into the path of the brickand intercept same, so as to hold it in the brick-receiving space.

Each block E and E is provided at its rear end with adownwardly-projecting pin w, the blocks 1) being provided withupwardly-projecting pins v these pins being located in the same verticalplane. The inner-face of the gear-ring B is provided with a series ofinwardly-projecting lugs provided with camsurfaces, as will behereinafter described. These lugs are located in two series, the membersof each series 7f 1; 7) If I If I)" 7) being separated from each otherby an angle of ninety degrees, as shown in Fig. IV. The series .5 &c.,consists of four pairs of lugs, each pair comprising an upper and lowerlug, as shown in Fig. IX. The upper lug is provided with a concaveinclined face forming an inclined plane which is adapted to contact theouter ends of the sliding blocks E and cause the same to be movedinwardly toward the center of the base-plate, when contact between suchface and such inner ends is effected. The lower lug of each such pair isformed with a similar concave face, but of a greater length than that ofthe upper, and is adapted similarly to engage the outer ends of theblocks D. The construction is hence such that the rotation of the ringin the direction of the arrow in Fig. I will effect a simultaneousinward movement of the blocks 1) and then a subsequent simultaneousinward movement of the blocks E and the knives E and E Each of the lugsof the series If is formed with the upper and lower cam-grooves (1" and6, respectively, such upper and lower grooves being identical in formand located in vertical planes. The forward end of these camg rooves isenlarged, so as to engage the pins c and a. knives are in their forwardposition, the construction being such as to cause these blocks andknives to be withdrawn simultaneously after having been acted upon bythe cam-surfaces of the series of lugs 7f, &c., as will be readilyunderstood. It will hence be seen that the rotation of the ring willeffect first the simultaneous movement of the clampingblocks, then thesubsequent simultaneous movement of the four knives, causing the latterto intersect the brick-receiving space, and then a simultaneouswithdrawal of all the knives and clamping-blocks.

The rear or outer ends of the slides F are each provided with anupwardly-projecting lug f, which is engaged by the cam-groove 6, formedupon the bottom of the ring B, as shown in Figs. 11 and IV. This grooveis formed with four cam portions 6 which are located at an angulardistance from each other of ninety degrees, as shown in Fig. 1V, andeffect a simultaneous forward and rearward movementof the slides. Thismotion of the When mounted, the blocks andslides is timed so as to takeplace immediately following the inauguration of the rearward movementorthe withdrawal of the blochsalul knives, the forward movement of theslides immediately preceding the forward or inward movement of theclamping-blocks.

The working face of each clamping-block is formed upon a separate platewhich is separated from the main portion of theblock by means of arubber plate d, and upon the middle working face of such working plateis secured a projecting spring d. which may be depressed into acountersunk portion or seatd. As shown in Fig. IX, we prefer to form theslides F in one piece, having a common upwardly-projecting lugf, suchconstruction contributing to the simplicity of the device.

The space intermediate of the knives, the clamping-blocks, and the barsF, and the discharging-opening (1 forms a path of travel for bricks, thelatter being caused to traverse such path preferably by gravity.

The operation of the above-described device is as follows: Assuming thatthe blocks and knives are in their withdrawn positions and that slides Fare in their forward or in tercepting positions and that a brick is insaid space and intercepted and held therein by means of said slides F,the spring guiding and centering same in such space, the ring B iscontinuously rotated, the clamping-blocks are now moved forward andcaused to securely clamp and hold the brick in the space awaiting theapproach and operation of the knives. During such action of theclampingblocks the guiding-springs(15 are depressed into their seats(5", and the elastic rubber plate (Z' prevents the crushing of thebrick, at the same time permitting a lirm holding thereof. The cuttingknives now advance and intersect the brick-space, chipping the upper surface of such brick on all four sides, thereby effecting the desiredresult. The continued rotation of the ring B now cli'ects a simultaneouswithdrawal of the knives and clamping-blocks, which is inn'nediatelyfollowed by the withdrawal of the slides F, which permit the dischargeof brick from the opening 4 Other modes of applying the principle of ourinvention may be employed instead of the one explained, change beingmade as regards the mechanism herein disclosed, provided the meansstated by any one of the following claims or the equivalent of suchstated means be employed.

It will hence be seen that the bricks are first arrested, then clampedin their path of travel, the cutting operation performed, and the bricksthen discharged, these operations bcing performed automatically andsuccessively in successive planes.

\Ve therefore particularly point out and distinctly claim as ourinvention-- 1. In a brick-facing machine, the combination ofautomatically-operating brick-arresting, brick-clamping, brick-cutting,and brickdischarging means.

2. In a brick-facing machine, the combination withautomatically-operating clamping means forminga brick-receiving space,of two sets of automatically-operating cutting knives respectivelylocated upon opposite sides of a brick while in such space.

- 3. In a brick-facing machine, the combination of brick-arresting,brick-clamping and brick-cutting means arranged to coact and means foractuating such means successively and automatically.

4:. In a brick-facing machine, the combination of reciprocable clampingmeans forming a brick-receiving space, 'reciprocable means below saidspace and arranged to intercept a brick while located therein,reciprocable cutting means arranged to intersect the latter and meansfor actuating said intercepting, clamping and cutting meansconsecutively.

5. In a brick-facing machine, the combination of reciprocable clampingmeans forming a brick-receiving space, reciprocabl'e means below saidspace and arranged to intercept a brick while located therein,reciprocable cutting means arranged to intersect the latter, andcontinuously rotatable means for actuating'said' intercepting, clampingand cutting means consecutively and intermittently. v
